To (ZZZ whom it may concern.-

Be it known that I, HENRY BUsHNEiL, a resident of the town of New Haven, in the State of Connecticut, have invented new and useful Improvements in Universal Joints for Axles, of which the following is a specification. 7

The object of myinvention is to provide a device or joint for mounting a driving-wheel on the forward axle of a locomotor or road? driving-wheel to the axle while its axis-is de flected from the axis of the wheel.

The invention consists in the novel universal joint hereinafter more fuily described and claimed.

- In the accompanying drawings, Figure 1 is an end View of a part of the front axle of a 10- comotor or road-vehi cle having a frictionwheel mounted midway upon it by means of Fig. 2 is a longitudinal section through the axle and friction-wheel,

of the wheel to the shaft. Fig. 31s an end view of the device with one of the bearingplates removed, and Figs. et and 5 show de- Referring to the drawings, a designates a wheel or pulley provided with friction V- grooves, and adapted to gear with a corresponding friction-wheel or series of wheels operated by the engines of a locomotor. The friction-wheel is mounted on the forward axle of the vehicle on a globular bearing, m, formed thereon midway between the wheels. Upon each side of the driving-wheels 1t is a bearing-plate, m bolted to the wheel and fitting the globular part of the axle, thereby forming a hearing which allows the axle to be deflected from the axis of the wheel in every direction. Each bearing-plate m has an exterior cylindricalbearing, k, which is adapted to fit in suitable hearings in the frame-work of the 10- comotor or vehicle, and which holds the wheel in alignment with the engine or motive machinery. The axial perforation through each wheel adjacent to the globular bearing. The

steps are held in place by the bearing-plates m, and are perforated radially. Each step receives a driving stud or pin, 0'', which is provided with a T-head, as shown. The T-heads of the driving-pins fit into opposite longitudinal grooves or slots, r, formed in the globular bearing m on the axle. As the driving-wheel n revolves it carries the axle around by means of the pins, and as the axle is deflected for the purpose of steering the vehicle the pins slide correspondingly in the grooves and oscillate in their steps, thereby allowing universal movement of the axle. v

I claim as new and desire to secure by Let ters Patent 6 In a traction-engine, the combination of the axle having a central globular bearing, m, provided with opposite longitudinal grooves or slots, r, the driving-wheel n, having opposite radial recesses adapted to receive the perforated radial steps T the pair of bearingsleeves m bolted, respectively, on opposite sides of'the driving-wheel and adapted to secure the steps in plac'e,'each having internal concave bearings fitting the globular part of the axle, and external cylindrical journals fitting fixedbe'aringsin the frame-work of the engine, and the oscillating .pins 1", journaled in the steps 1, and having rectangular heads fitted in the slots, all arranged and combined substantially in the manner and for the purpose speoified.
